I converted 3.55 CFW / Kmeaw to 3.55 DEX Rogero then updated to 4.21 DEX to play my original Tekken retail Blu-Ray (BLES01702).
It worked fine - but now I heard of the TTT2 JPN pkg fix allowing the (TTT2 PSN by DUPLEX) to work on 3.55 CFW.

My question how or if I can get my TTT2 disc/back up working on 3.55 CFW? Will putting the JPN pkg fix in the HDD0 make TTT2 work on 3.55 CFW Kmeaw? or

Do I need to convert TTT2 (BLES01702) to PSN? How can I convert to PSN using ASTools 3.1? And can I play TTT2 of USB HDD?

Any way guys to play TTT2 of HDD0 or USB HDD without using disc on 4.21 / 4.20 DEX
